ran max spool 17 with thunder products clutching and she was a runner. 1100t snow drag sleds on the 2 step and 60’ mark I was passing them already.

If you zoom in an look to left of gauge you can see the stick on plate. I stick it right on that and go. The accuracy is close. And running a tuned sidewinder it’s much better than a buddy saying. I think you’re 10sled lengths in front vs I think you’re 12 sleds in front now! You can see effects...

I have had max spool 17 with closed loop on mine, cold air, 2.5 super quiet, 3 bar and bov. My fathers srx and my rtx got within .2gal of eachother when we filled up after 90 miles. And for rest the season we were close to exactly same gal every fill up. After that I can’t confirm if his stayed...

Blew clutches apart (not the original) that made a mess so busy few weeks coming. In progress: Pro4 primary Thunder built secondary all new Ns1 gauge Wastegate Flasher with new multi bundle from ms17 single tune with launch control Still need: (have any lmk) New Stock belt guard New belly pan...

Got ya, yea I had secondary bolt and adjuster come out and knock my primary mid winter then my replacement primary shed all the weights and took secondary with it. So pro4 4 weight and a brand new Yamaha secondary for me. I considered tapp but was pushed toward pro4, told tap is great but the...

Why switch from Yamaha secondary? Nothings wrong with that. Team clutches have struggled though. I have a pro 4 on the way myself. And a brand new Yamaha secondary ground up build

No idea. It’s possible I am sure As far as viper Idk that either. Message a Mike Duhr on Facebook that’s who is doing this.

From what I gather yes, but need diff parts and diff ways to splice in. I obviously don’t know the details but he seems pretty ontop of it. All I know is what I shared there

It’s a standalone ecu for the ps, needs to splice to power ecm and give it signal. Besides that it’s all plug and play replacement parts

Have you physically done this yet or this the “this should work” stage? Just know this guy has done them and said roughly how he goes about it.

There’s a guy in Michigan or Wisconsin that is doing the conversion, pre 19 needs to be spliced into harness and he has stuff made up but he does all the installs.19 and newer is just replacing the wire harness with the ps one. It’s nice that it’s the factory version but it costs more than the...

I don’t get the turbo 2stroke excitement. These 850-900’s are unreliable enough as a long term trail sled. Now let’s make them more volatile and add turbo that makes 10hp and much more it can’t run pump fuel and/or gas life span of 1000-1500 miles.

Mine just arrived. Said it was 36 hours per gauge of 3d printing with no errors to make all the pieces. So he may be behind or waiting on displays maybe.

another company makes them for d&d, I believe bikeman, speedwerx, SSI and few others make magnet weights.

Thunder products orange secondary and primary springs with their rollers, you can buy the 35/39 Dalton helix however you already have a 35/39 helix from factory. I would actually suggest a straight 35 from Dalton, 1 it’s the best option for all levels of tunes and performance consistency it...

That looks like an xpt to me. And I would run 8-1” all day long. Take longer to wear out as it’s spread out in more surface area too. Aslong as your arms are up for it I go as I can. I personally run 10” shapers on c&a xcs on front of my sidewinder

That’s a great plan till you have them about touching an any movement will bounce them off eachother. Also I do t want a 20-25,000 sled going through the tin on a 15-20-25,000 trailer because I didn’t wanna use a $10 strap. I do know a lot don’t use them and also seen the carnage of it when...

I’m curious how you plan to tie them down if the bumpers are all touching and skis straddling the one infront. I have a 129 sidewinder and bought the mrs a 137 vr1, my 23’ inline fits 2 driving in from back staggered in the 18’ box without getting in the v. We went to maine year ago and with...

Got ya, yea the air from vacuum lines in the solinoid should actually force the wastegate shut untill the ecu says to open. Are you sure it’s not leaking out elsewhere since it bleeds down? Also without sled running it won’t make vacuum pressure to close the wastegate and hold it shut, I believe.
